Hi folks, I'm new to Amazon seller central and have managed to successfully list some products to my Amazon UK store which are also available in Europe.

However, when I click Edit beside my product and scroll to the bottom to "Manage offers in other marketplaces" section, I can see "Sell In USA" and "Sell In Canada" options, when I activate these and try to click submit, I get a red error message under my "Merchant Shipping Group" tab no matter what option I select. (see attached images).

I've tried editing my shipping template by adding these regions, this seems to work when I go back into to edit my product but only if I completely remove the Merchant Shipping Group field and leave it blank, when I click submit I then get a success windo telling me it'll take 24 hrs to come into affect. However when I have a look in the Edit product page, everything appears to revert back to just the original listing?

I contacted both Amazon UK and USA about this but have not been given any solid advice on how I can actually sell my product in these regions?

Anyone any idea what I should do?

Thanks
